Amino acid-based compound fertilizer

Question: Is gaseous ammonia or liquid ammonia better for the amino acid method? Why? Can the ammonia axis ventilate both ammonia and steam simultaneously?
The amino acid method should involve aeration of ammonia; at least that’s what I’ve seen in both tubular reactors and packed-bed systems.
Then may I ask if the ammonia shaft can handle both steam and gaseous ammonia?
Using gaseous ammonia is better, as ammonia exists in a liquid-gas mixture state, and existing flow meters cannot measure it accurately; it can only be measured precisely when converted into a liquid or gas state.
Both gaseous ammonia and liquid ammonia can be used; using liquid ammonia eliminates the need for heat from vaporizing the liquid ammonia. The ammonia shaft can handle both liquid ammonia and steam, but check valves must be installed on each pipeline.
Liquid ammonia is used with double-buried pipes, while gaseous ammonia is used with tubular reactors.
